title: Fast screening of stabilizers in polymeric materials by flow injection-tandem mass spectrometry.
abstract: In the present study, the applicability of rapid flow injection-triple quadrupole mass spectrometry for simultaneous qualitative screening of different classes of stabilizers in polymeric materials is demonstrated. Electrospray ionization and atmospherical pressure chemical ionization were compared, whereby the latter yielded generally poorer detection limits and only single charged ions that were for some analytes beyond the mass range of the quadrupole mass spectrometry. Positive electrospray ionization allowed the interference-free monitoring of multiple reaction monitoring transitions selective for 36 commonly used stabilizers without chromatographic separation. Real polymer samples were extracted by toluene and the method allowed the detection of analytes down to 0.00001-0.025 wt% depending on the stabilizer.
